The #17760 Reverse Mounting Ring allows products with an OPTEC-3000 Receiver to be mounted to the threaded side of IFW systems. This allows the IFW to be mounted in reverse orientation and at whatever angle of rotation is best for the entire optical setup. No longer will you be limited to working with whatever orientation a tightly-screwed thread gives you!
